A) Overall distance error (average over all trials and blocks 2–3) for the landmark-tethered object (red) and boundary-tethered object (blue), for the CA (light colors) and WS (striped colors) groups. Distance error for the CA and WS groups is re-plotted from Figure 3A and Figure 2A, respectively. Compared to the CA group, WS participants were significantly impaired at replacing the boundary-tethered objects but not the landmark-tethered object. B) Relative influence of the landmark on landmark-tethered and boundary-tethered object replace locations, for the CA and WS groups. Landmark influence for the CA and WS groups is re-plotted from Figure 3C and Figure 2C, respectively. Compared to CA adults, WS participants were more influenced by the landmark for the boundary-tethered object, but not the landmark-tethered object. All error bars indicate ±1 SEM.
